He also was featured on Marilyn Manson’s breakthrough album Antichrist Superstar, as was most of Nine Inch Nails due to Trent Reznor’s ‘musical mentor’ relationship with Manson. Lohner can be heard playing the acoustic guitar on the track “The Reflecting God”.

Additionally, he does remixes for various artists under the pseudonym Renholdër (“re:d.lohner” backwards) such as the song of the same title featured on A Perfect Circle’s debut album Mer De Noms. He is currently a studio member of A Perfect Circle, helping with engineering and filling in for instruments and vocals as necessary. He has appeared in all of their albums to date in one form or another, although in 2006 the band was on hiatus as Maynard James Keenan worked on the new Tool album and toured.

During 2003, Lohner worked with Richard Patrick of Filter, Wes Borland of Limp Bizkit, and Josh Freese of A Perfect Circle in a project called The Damning Well. A total of 14 songs were recorded (half of which featured Amy Lee of Evanescence on vocals instead of Richard Patrick), but only one of these has been released (‘Awakening’) which was featured on the soundtrack for the movie Underworld. So far, there have been no plans to release the rest of the songs.

In 2005 and 2006, Lohner was involved with Wes Borland in a project called Black Light Burns, where he took on the role of producer as well as playing guitar, bass, synth, programming, etc. Other members include Josh Eustis of Telefon Tel Aviv and Josh Freese. A release was planned for early 2006 through Geffen Records, with expectations of a subsequent world tour.
